GAS SAVING ATTAGHMENT FOR INTERNAL COMBUSTION ENGINES Filed Sept. 27. 1928 Patented Mar. 11, 1930 HENRY FRANK BEEMAN, 015 FORT COLLINS,COLORADO GAS-SAVING ATTACHMENT FOR INTERNAL-COMBUSTION ENGINESApplication filed September 27, 1928. Serial No. 308,868.

This invention relates to a gas saving attachment for internalcombustion engines and is designed primarily for use in connection withautomobile engines.

One of the objects of the invention is to operation of the engine.

A further object is to provide simple means for washing the. vapor so asto prevent the particles of dust from being carried into the engine andinjuring the same.

A further object is to supply water vapor to the intake manifold,thereby permitting a considerable reduction in the amount of gas usedand also practically eliminating oarbon deposits.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed may be made within thescope of what is claimed, without departing from the spirit of theinvention.

In the accompanying drawings, the preferred form of the invention hasbeen shown.

In said drawings,

Figure 1 is view partly in elevation and partly in section of a portionof an automobile engine having the present improvements combinedtherewith.

Figure 2 is a perspective view showing one way in which the intake pipeof the attachment can be connected to the overflow pipe of the radiator.

Referring to the figures by characters of reference A designates aportion of the intake manifold of an automobile engine and B designatesa portion of the radiator provided with the usual overflow pipe G.

The attachment constituting the present invention includes a tubularbody 1 preferably formed of thick glass the ends of which are seated ingrooves 2 formed in heads 3 and 4:. These heads are drawn toward eachother by tie rods 5 and, by first placing gaskets 6 upon the ends of thetubular body 1, the ti ghtening of the rods 5 will-result in theformation of a shield chamber 7. Opening through i the upper head 3 ofthe attachment is a nipple 8 to which is connected an outlet tube 9which can be of copper or other material easily bent. Another tube 10 issuspended within the chamber 7 from the head 3, the upper end of thistube being coupled as at 11 to a vapor supply tube 12 likewisepreferably formed of copper or other material easily bent. An air inlettube13 depends from the head 3 and has a check valve 1 1 normally closing the upper or outer end thereof. The

lower end of this tube 13 is located at a considerable distance abovethe lower end of the tube 10 and mounted to slide within the air tube 13is a rod 15 projecting upwardly from a float 16. This rod is soproportioned that when the float 16 rises to a point close to the lowerend of the tube 13, said rod 15 will come against and unseat the checkvalve 14, thereby permitting air to enter the chamber 7 through the tube13., Normally, however, this valve is in closed position.

When it is desired to use the device constituting the present inventiona small opening 17' is drilled into the overflow pipe 0 and an elongatedopening 18 is out into the tube 12 near its free end. A screw plug 19which is coupled in any suitable manner to one end of the tube 9 isscrewed into an opening 20 drilled in the wall of the intake manifold A.The opening 18 in tube 12 is placed where it will communicate with theaperture 17 and thereafter said tube 12 is fastened securely to theoverflow tube 0 in any suitable manner. For example strong insulatingtape indicated generally at 21 can be wrapped about the engagingportions of the tubes 12 and C so as to hold them together firmly, closethe free end of the tube 12 and prevent leakage of air into the tube 12.With the parts thus assembled and the body land heads 3 and 4 mounted inany preferred manner adjacent the ention between the upper portion ofsaid chamgine, the attachment is ready for use. It is her and the intakemanifold of an engine.

rst necessary to pour a mixture of heavy oil In testimony that I claimthe foregoing as into the chamber 7. This mixture is prefermy own, Ihave hereto affixed my signature. ably made up of one part coal-oil andtwo HENRY FRANK BEEMAN. 70 I parts castor oil. A suflicient amount ofthe mixed oil is used to submerge the lower end if of the tube 10. Whilethe engine is in use a suction will be set up from the chamber 7 10through the tube 9 to the intake manifold A 75 and as the check valve 14is normally closed, this suction will result in the withdrawal of anamount of vapor from the top ofthe radiator B through the upper portionof the over- 15 flow pipe C, the apertures 17 and 18to the S0 tube 12and thence into the bottom. portion of chamber 7. Here the vapor willrise through the oil at which time any dust or other objectionableparticles commingled therewith 20 will be precipitated while the purevapor will 35 be free to flow into the tube 9.

Should there be an undesirable accumulation of water due to thecondensation of vapor in the chamber 7, the float 16 would zti'risesufiiciently to lift rod 15 and valve 14 90 and thus admit air into thechamber 7 so that l the'operation will continue without causing l thechamber to become flooded to an objectionable extentbyithe water. [Airthus admitted 'willalso prevent the structure from vas overheating.

It will be understood that the pipe or tube 1'3 acts as a guide for therod'15.
